    Hello Jon,

    Just to clarify, the FUSE protection was triggered through a permanent failure, correct?

    Is Settings:Protection:Protection Configuration[PF_OTP] bit set to 1 in the device configurations? If this is set to 1, then there will be no way to clear the triggered FUSE protection as the device will program in the permanent failure status.

    If the bit is not set to 1, then the device will store this permanent failure status into RAM which can be cleared by a full reset or even a partial reset through the RST_SHUT pin. 

    If you no longer want the device to assert the FUSE pin when a permanent failure occurs you can set the Settings:Protection:Protection Configuration[PF_FUSE] bit to 0 on your configurations. The device will still provide a flag to indicate a permanent failure has occurred, but will no longer assert the FUSE pin.

    Regards,
